Difference between command line cURL and PHP cURL

I have a cURL command like this:

curl 'https://www.11880.com' -H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.70 Safari/537.36' -H 'accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3' -H 'accept-language: de-DE,de;q=0.9,en-US;q=0.8,en;q=0.7'

Executing this in a command line like in Terminal app on my Mac, results to the expected output.

(In case you test it yourself: If this output contains the word Sicherheitsüberprüfung it's geo blocked and you have to use a German IP to test it.)

I transferred the exact command to PHP cURL like this:

<?php
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://www.11880.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');

$headers = array();
$headers[] = 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.70 Safari/537.36';
$headers[] = 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3';
$headers[] = 'Accept-Language: de-DE,de;q=0.9,en-US;q=0.8,en;q=0.7';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>

When I run this code I'm getting a message that my request was recognized as automated request/robot: It says Sicherheitsüberprüfung, means security check.

Of course, I'm using the same IP for both, command line and PHP cURL request.

Why that? Isn't command line cURL the same as PHP cURL?

Or is there anything wrong with my PHP script?

UPDATE

I fortuitously found out the following: I'm using Coda as code editor on my Mac. This has a build-in PHP rendering engine. Using this with my PHP script, the result is as expected. It's the same result I'm getting in the command line.
